msuryawanshi05/network-protocol ? reverse-engineered prompt

Build me a small networking tools suite with three separate apps in one repo.

First, a packet sniffer and live network visualizer that passively watches TCP traffic, shows a simple breakdown of what is happening at each network layer, logs DNS activity, spots nearby devices with ARP, and draws a live topology view in the browser. Use a Go backend and a lightweight Python web app for the dashboard.

Second, a multi client TCP chat app where a server can handle several people at once, let them message in real time, and support room style broadcasting. I want a simple terminal client, and if it makes sense, a basic GUI client too.

Third, a port scanner and attack detection tool with a desktop GUI. It should scan local or remote ports, detect obvious scan or flood patterns, keep a basic baseline, and let me view or manage Windows firewall rules from the app. Use a Go backend and a Python desktop interface.

Make it runnable on Windows, keep the UI simple, and look up current docs online if you need to.
